Open the attached test case.
You'll see that the second glyph in each box is off to the side.

I discussed this problem with Hyatt and he figured out where the bug is. 
In RootInlineBox::ascentAndDescentForBox there are cases where we compute ascent and descent without passing the baseline type which causes an incorrect computation in case of ideographs.
